truck body from which shoveled. I

Another object of the invention is to so construct the grid that When placed in the upper end of the hopper it will readily assume its proper slanting position therein and maintains such position without requirement of securing bolts during operation.

Other objects and advantages of the invention will appear in the following description.

1 the sand was previously 25 shown in the accompanying drawing, inwhich:

Fig. '1 is a perspective view ofa sand distributing appliance with the invention applied thereto; i l

Fig. 2 is a side elevation of the sand distributing appliance including the invention, the sand distributing appliance being mounted upon a truck body in position for use; and

Fig. 3 is a fragmentary side view of a hopper for the sand distributing appliance and the invention positioned therein, the view being in vertical section. I

The sand distributing appliance illustrated is of a well known type that generally has a sup porting frame 5 provided with elbow arms 2 that extend from its forward upper end, said arms being provided with corresponding clamp members 3 so that when the sand distributing appliance is in operating position in connection with a vehicle body A, the frame rests against the tail gate or wall 5 of the body and the arms 2 depend into the body and the clamp members are screwed against the inner face of the tail gate, thus holding the sand distributing apev pliance in place;

The frame has mounted therein a hopper 6 that is pivotally mounted upon a rod 1 the ends of which are secured in the front and back of the frame at the upper end thereof. The hopper has oscillatory movement on the rod and is yieldingly held in one extreme position by a tension spring hopper is An illustrative embodiment of the invention is \tered upon the road.

3 that is secured at its ends respectively to the hopper and the frame, and is moved to its other extreme position in opposition the spring by a cam to restraint of 9 that is secured on a driveshaft l0, and bears against a friction plate H on the hopper.

Thus, when the drive shaft is rotated the hopper accordingly is vibrated. A

- nozzle I2 is adjustably mounted in the material from the there being a gate valve [3 14 for controlling of the frame I through which discharged, provided with an operating rod lower end the discharge of material from the hopper.

The drive shaft I0 is means, such as a crank l5, that is with the shaft by gearing (not shown) in the gear case [6. Or, if preferred,

actuated by any suitable connected 1 contained any suitable motor (not shown) may be used instead of the crank operated gearing.

Upon the lower end of the drive shaft I0 is concentrically secured a scatter-wheel consisting of a disc ll 9 having secured upon its upper face a series of radially disposed blades I8, so that whenthe wheel is rotated and the material passes onto the wheel from the nozzle, the material is scatand back walls IV-6" of the hopper diverge upwardly, and the upper end of the frontwall 6 has securedalong its top an angle iron IS,

the upper flange of which extends inwardly respecting the hopper, and is for the purpose hereinafter set forth.

The grid attachment is constituted of a rectangular frame the rear end of which slants upwardly and outwardly, and the front end is formed of a plate constituting a chute 2| that has secured to its rear under side, extending parallel therewith and transversely respecting the frame, an engaging bar wardly extending I flange 23 spaced lower face of the chute 2| so that when 22 provided with a forfrom the the frame is positioned in the hopper the flange extends beneath the upper flange of the angle iron l9 while the rear end of the slanting inner are spaced apart other and extend over onto the top of the ably secured thereon.

In use, the sand cured preferably to the tail gate 5 of body and clamped in face of the back wall the-hopper. In this manner the frame is Secured in connection with the frame 20 are a series of grid bars 24 that in parallel relation with each from the rear end of the frame chute 2| and are suit- 5 the frame 20 rests against 6' of locked 5 distributing applianceis sethe truck position thereon by tightening the clamp members 3. Thescatter-wheel is then set in motion by turning the crank l5, and while the truck is in motion the abrasive material is manually shoveled onto the grid. The undersize material passes through the grid and falls into the hopper and is kept agitated while passing therethrough by the vibratory action of the hopper, and from thence it is discharged through the nozzle onto the scatterwheel by which it is distributed over the surface of the roadway. The oversize material, upon failing to pass through the grid bars, aided by the vibratory action of the hopper, slides downwardly over the grid bars and the chute back into the truck body.

When it is desired to remove the grid it is only necessary to raise the rear end of the grid frame and move it rearwardly so as to remove the flange 23 from engagement with the angle iron l9, and then lift the grid bodily from the hopper. In replacing the grid it is held above the top of the hopper with the chute resting upon the angle iron I 9 and then moved upwardly so that the flange 23 is moved under the inturned flange on the angle iron while the rear end of the grid is dropped down into position against the rear wall 5" of the hopper.

What I claim is:

In an apparatus of the class described a vibratory hopper having upwardly divergent front and rear Walls, the rear wall extending above the front wall and being downwardly and forwardly inclined, the front wall having an inwardly directed flange at its top; the combination therein of a screen grid provided with a frame and having a chute at its forward end, resting on said flange, an angle member secured to the bottom of said chute and having a forwardly extending portion engaging the underside of said flange, the rear edge portion of said frame resting on the inner face of said rear wall below the top thereof.
